Hello, I hope all is well with you.
I have 3 questions about Matpower SE package and I would be so grateful if you could help me in this regard. Sorry for the number of questions. 1) When I change the input measurements of the SE for 14 bus and make them random with the standard deviation of 20%, still, most of the estimated voltage magnitudes are rather the same. For example, the value of bus 1 is 1.06 always and others just change a little. As another example, one just changes in this interval [1.04,1.05]. Others are the same. But the voltage values can be [0.95,1.05] as I know ([0.94,1.06] in Matpower setting). I also noticed that the power flow with random load values also can't change the voltage values reasonably and the voltage values are constant. I run 10000 times. Where is the problem? 2) How can I use a different type of measurements? I want to change the available measurements and do SE based on some flow measurements and also injection measurements but the existing available measurements are generations, flow measurements, and voltage measurements. Most of the papers use flow measurements and injections as available ones. 3) How can I simulate an outage (line, etc.) in this estimation code? Thank you very much for your help and time. Best Wishes,
